Hypoventilation may be caused by an uneven distribution of inspired air (as in bronchitis), obesity, neuromuscular or skeletal disease affecting the thorax, decreased response of the respiratory center to carbon dioxide, or a reduced amount of functional lung tissue, as in atelectasis, emphysema, and pleural effusion.
Seborrheic Keratosis Causes Wart Like Skin Growths. Seborrheic keratosis causes wart like skin growths to appear on just about every body thatâs over age 40. Although they resemble skin cancer, these keratosis tumors are benign.
They form when HPV forces your body to make excess skin cells. This seems innocuous, but there's no place for those cells to go; as a result, they form bumps on your skin or grow inward, which can be painful. There are several different types of warts. The most common warts are those that form on the hand or knee; these are known as verruca vulgaris. They develop as hard bumps on the skin and tend to be pink or brown in color. They can develop as a single entity or in small groups [source: Bupa].
